Daily Mail is a tabloid newspaper, one would hope our media doesn't follow their lead. BTW "Climategate" isn't as big of a deal as you think it is and there isn't much mischief going on.
They're merely disregarding usage of tree rings to ascertain temperature measurements. I would have done the same. Why use a method that tells something different from temperature you've recorded with a thermometer? I would move alone if I were one of you people.

The divergence problem is the disagreement between the temperatures measured by the thermometers (instrumental temperatures) on one side and the temperatures reconstructed from the widths of tree rings on the other side, in the northern forests.
While the thermometer records indicate a substantial warming trend, many tree rings do not display a corresponding change in their width. A temperature trend extracted from tree rings alone would not show any substantial warming. The temperature graphs calculated in these two ways thus "diverge" from one another since the 1950s, which is the origin of the term.
